When the traditional glue coating equipment works, it usually directly coats the glue with a glue coating roller, ignoring the cleaning of both sides of the board core. Once there is dust on both sides of the board core, it will affect the adhesive effect after the board core is coated with glue and reduce the product quality of the polyurethane board, which needs to be improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] As Figure 1 , Figure 2 , Figure 3 shown, a gluing device for producing polyurethane boards includes a frame 1, an upper transmission rack 2, a lower transmission rack 3, transmission rollers 4, a dust suction mechanism 5, a cleaning mechanism 6, and a gluing mechanism 7.

[0030] As Figure 1 , Figure 2 , Figure 3 shown, the frame 1 is arranged on the ground, the upper transmission rack 2 is horizontally arranged above the frame 1, and the lower transmission rack 3 is horizontally arranged below the frame 1. The transmission rollers 4 are rotatably connected to the upper transmission rack 2 and the lower transmission rack 3 at intervals, and the upper and lower transmission rollers 4 are used to clamp and transmit the polyurethane board core.

[0031] As Figure 2 , Figure 3As shown, the dust suction mechanism 5 is arranged at the front end of the upper transmission rack 2 and the lower transmission rack 3, and is used for adsorbing and cleaning the dust on the surface of the polyurethane board core. The dust suction mechanism 5 includes a dust suction pipe 51 and a pair of dust suction covers 52. The pair of dust suction covers 52 are arranged on the upper transmission rack 2 and the lower transmission rack 3 with their openings facing each other, and the dust suction pipe 51 is connected to the pair of dust suction covers 52.

[0032] As Figure 2 、 Figure 3 shown, the cleaning mechanism 6 is arranged in the middle of the upper transmission rack 2 and the lower transmission rack 3, and is used for wiping and cleaning the surface of the polyurethane board core. The cleaning mechanism 6 includes a pair of support frames 61 and a pair of cotton cloth heads 62. The pair of support frames 61 are arranged on the upper transmission rack 2 and the lower transmission rack 3, and the pair of cotton cloth heads 62 are horizontally arranged at one end of the pair of support frames 61 close to each other, and are used for abutting against both sides of the polyurethane board core.

[0033] As Figure 2 、 Figure 3 shown, the glue coating mechanism 7 is arranged at the rear end of the upper transmission rack 2 and the lower transmission rack 3, and is used for coating glue on the surface of the polyurethane board core. The glue coating mechanism 7 includes a pair of glue coating rollers 71. The pair of glue coating rollers 71 are rotatably connected to the upper transmission rack 2 and the lower transmission rack 3, and are used for abutting against both sides of the polyurethane board core.

[0034] When it is necessary to coat glue on both sides of the polyurethane board core, the polyurethane board core is placed between the upper and lower transmission rollers 4, and the transmission rollers 4 are used to drive the polyurethane board core for transmission. Subsequently, the polyurethane board core first passes through the position of the dust suction mechanism 5. At this time, the dust suction cover 52 can adsorb the impurities and dust on the surface of the polyurethane board core, realizing the preliminary cleaning of the surface of the polyurethane board core.

[0035] Subsequently, the polyurethane board core is transmitted to the position of the cleaning mechanism 6. At this time, the cotton cloth heads 62 wipe and clean both sides of the polyurethane board core, realizing the thorough cleaning of the surface of the polyurethane board core and ensuring the cleanliness of the surface of the polyurethane board core. Finally, it passes through the position of the glue coating mechanism 7. At this time, the pair of glue coating rollers 71 simultaneously perform glue coating operations on both sides of the polyurethane board core, realizing the one-time glue coating at both positions and improving the production efficiency.

[0036] Therefore, by setting up a glue coating device that can timely perform dust suction treatment and wiping treatment on the polyurethane board core, the cleanliness of both sides of the polyurethane board core before glue coating is ensured, so as to ensure that the glue can be stably coated on both sides of the polyurethane board core, thereby ensuring the later adhesive effect and improving the product quality of the later formed polyurethane board.

[0037] As Figure 1 、 Figure 2As shown, sliders 21 vertically slidably connected to the frame 1 are provided on both sides of the upper transmission rack 2 and the lower transmission rack 3. A driving mechanism 8 for controlling the vertical sliding of the sliders 21 is provided on the frame 1. The driving mechanism 8 includes a pair of bidirectional screws 81, a pair of sprockets 82, a chain 83, and a handwheel 84.

[0038] As Figure 1 , Figure 2 shown, a pair of bidirectional screws 81 are vertically rotatably connected to both sides of the frame 1. The two sliders 21 on each side are threadedly connected to the bidirectional screws 81. The sprockets 82 are provided at the upper ends of the bidirectional screws 81. The chain 83 is wound around the pair of sprockets 82. The handwheel 84 is provided at the upper end of the bidirectional screw 81.

[0039] When gluing polyurethane board cores of different thicknesses is required, the handwheel 84 is controlled to drive the bidirectional screw 81 to rotate. At this time, under the combined action of the sprockets 82 and the chain 83, the pair of bidirectional screws 81 rotate synchronously, and the relative movement of the sliders 21 on the upper and lower layers is controlled, so as to realize the adjustment of the distance between the upper transmission rack 2 and the lower transmission rack 3, thereby adapting to the gluing of polyurethane board cores of different thicknesses and improving the practicability of the gluing device.

[0040] As Figure 1 shown, conveyors 9 are horizontally provided on both sides at the rear position of the frame 1. The conveyors 9 are used to clamp both sides of the polyurethane board core. Therefore, after the polyurethane board core is glued, by providing the conveyors 9 that clamp both sides of the polyurethane board core, it is avoided that the glue on both sides of the polyurethane board core is touched during the transmission process, ensuring the stability of the gluing process, and at the same time ensuring the later gluing effect and improving the product quality of the later formed polyurethane board.

[0041] As Figure 1 shown, anti-slip spikes 91 for piercing into both sides of the polyurethane board core are provided on the conveyors 9 to increase the stability between the conveyors 9 and the polyurethane board core and ensure the stable transmission of the polyurethane board core. At the same time, since the edge position of the polyurethane board core needs to be cut later, even if it is pierced into the polyurethane board core, it will not affect the later use of the polyurethane board core.

[0042] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. Those skilled in the art can make modifications without creative contributions to the embodiments according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
